Chauncey Cohen was brought to Good Samaritan Hospital by his mother, Tania Merisca, in June 2013.

The boy, who had been staying at the Holiday Inn Express with his mother and her boyfriend, Antonio Durham, was unresponsive and later pronounced dead.

The cause of death was determined to be blunt force trauma to the abdomen and the manner of death was homicide.

Durham was charged with murder after he was arrested in Fall River on Monday. Merisca was taken into custody in Brockton. She was charged with being an accessory after the fact.

Dunham and Merisca are scheduled to be arraigned Tuesday in Brockton District Court.

"He was like family," said Takara Askew, a relative of the boy's biological father. "It brings back memories of what we dealt with eight to nine months ago. It's like a fresh wound being sliced back open again."

At the time of the boy's death, Merisca said she left her son with Durham while she went to work.

"For this to happen is such a tragedy. I wish I had called in sick," Merisca said.

After her shift, Merisca said her son did not feel right and she gave him a warm bath at home.

"I wrapped him up. His face was getting cold, and then his eyes just went back," she said.

Merisca said Durham drove her and the child to the hospital then left.

"He was a happy kid, a really happy kid. I am so sad I cannot bring him back," Merisca said.
